Diversity and distribution of Neotyphodium-infected grasses in Argentina
In the present work, we studied the presence of "epichloë/neotyphodium endophytes" in native grasses from Argentina. An extensive area of this country, representative of several different environments, was studied. Nine new host species of the genera Briza, Bromus and Poa were observed to...

An extensive area of this country, representative of several different environments, was studied. Nine new host species of the genera Briza, Bromus and Poa were observed to be infected with asexual seed-borne endophytes. Epichloë stromata were not observed on any grass species. The incidence of infection in natural populations was highly variable among host species and among populations of the same host species.
